As you can imagine, more people are reading The Jerusalem Post than ever before.
NBC News was not able to independently verify the claims.
German media earlier reported that hackers had posted data including credit card details and mobile phone numbers, with politicians from all major parties affected apart from the right-wing Alternative for Germany (AfD).
The German government warned that some of the leaked documents could have been doctored, and said it's still verifying all the leaked data.
"There is evidence of a number of phishing attacks and data leaks collected over a sustained period of time", he said. "We are in close contact with the security authorities", the spokesperson said.
Screenshot taken on January 4, 2019 shows (party blurred) data of German Chancellor Angela Merkel as they were published via twitter, as part of a massive leak of private data stolen from German politicians, that have been released online in December 2018.
"With regard to the Chancellery it seems that judging by the initial review, no sensitive information and data have been published and this includes (from) the chancellor", a government spokeswoman told reporters. Other leaks, for instance, featured a chat exchange between Robert Habeck, leader of the Greens, and his wife and children.
The advent calendar-style releases, from 1 December to 28 December, started by featuring information on TV presenters, then rappers, and focused on politicians from 20 December. Security firm Trend Micro has linked the Bundestag attack and others to Pawn Storm, a group with ties to Russian Federation - whose government has repeatedly denied it's hacking foreign powers.
Germany's BSI federal cyber agency said Friday it was as yet unclear who had perpetrated the hack.
A defence ministry spokesman said the armed forces had not been affected by the breach.
Public broadcaster RBB said the data was tweeted out by a Twitter account over the weeks before Christmas, althiough it was only discovered last night.
The city-state of Hamburg was working with Irish data protection authorities to stop the data being spread via Twitter, but said the company had not been responsive. Spiegel reported that the Twitter account only followed a couple of others, including anonymousnews.ru, a site known for spreading far-right hate speech.
Germany's Bild newspaper, in turn, cited sources in the BSI, the country's state security agency, as saying that the German government's secure internal network was not compromised in the hacking incident.
